In production planning system , the features and contents of annual production planning , monthly planning , weekly planning and day assembling planning are discussed , and heuristic algorithm is applied in resolving the model of weekly planning and day assembling planning 在生产计划系统中，重点探讨了年度生产经营计划、月生产计划、周生产计划和日装配作业计划的特点与内容，并将启发式方法应用于周生产计划和日装配作业计划模型的求解。
Moreover , this paper testifies the conclusions of theoretical discussion by a logistics case , and illustrates the efficiency of solutions in every phase , the decision continuity between phases and the guidance significance of final solution to practical distribution operation 最后，本文以一个物流实例为对象进行实例分析，佐证理论探讨的结论并体现各阶段求解方案的有效性、阶段之间决策的连续性以及解决方法对制定实际配送作业计划的指导价值。
Making the dispatched policy has not the optimization and programmed techniques for its features of none structure , multiple objective and stages decision making . so it is difficult to do it through the computer . now the computer is n ' t used widely in this respect 由于调度作业计划决策具有非结构性强、实时性强、属于多阶段、多目标决策等特点，难以采用优化及程序化决策技术，所以难以用计算机技术来实现，而使计算机在此方面的应用几乎处于空白状态。
In order to verity the scheduling result , the paper has designed the simulating module of workshop scheduling . through the method of acd ( acd - activity cycle diagram ) , the paper brought forward the simulating model of workshop . the paper adopts activity scanning method to simulate the execute 基于活动循环图法,建立了车间作业运行过程仿真模型;通过活动扫描法模拟作业计划的执行情况,对计划与调度结果进行仿真分析与综合评价,从而进一步改进计划与调度方案,实现计划调度过程的全局优化。
Taking the carton manufacturing industry as an example , based on the development of production scheduling and its present status of application home and abroad , we attempt to make some research on the characteristics in the production process of mixture industries , and the characteristics , the existing problems and the system structure in the production scheduling of mixture industries 本文在总结和分析国内外生产作业计划的发展和应用现状的基础上，以纸箱生产行业为例，研究了混合型企业生产流程的特点，生产作业计划的特点、研究现状与体系结构。
In order to study the problem of automatically making railway locomotive station operative plan and making a high quality plan , above all , we ought to analyze the operation system of the station , know thoroughly the procedures of operation system and make acquainted with regulations of all the work of the stations 要研究计算机自动编制阶段计划，必须分析铁路区段站的作业系统，通晓区段站作业系统的工作过程，找到区段站中作业组织之间的规律，才有可能编制出理想的作业计划。
